I just purchased my first duplex and didn't even think about trying to self manage even the first - so a big tip of the hat - keeping that extra bit in the beginning and reinvesting can really make a big difference but I knew with my work schedule it wouldn't be fair to the tenants to not have a professional available to work with during normal business hours and a local to call for emergencies.

I'd need to acquire/build the following (local zoning and permitting allowing):-A 10-15 acre parcel-Main gated entrance with office building nurse's station and leasing offices-Possibly a second gated entrance at the opposite end for emergency services-A common area with garden surrounded by a circle of buildings including a dining hall, cafe, "office building" (fake offices with toy phones, etc), small movie theater and a rec center-A large, two story apartment building with medical facility (for those with late stage conditions)-Two small "suburbs" of tiny homes for higher functioning residents (stand alone studio apartments with no kitchen for safety reasons).  

But what they've done is opened up applications for ERAP (Emergency Rental Assistance Program) again, despite publicly declaring there is no money left to be issued.  

That way if they send you something after hours you have the choice to decide if it's something that is in fact an emergency or something that can wait until tomorrow.

I also maintain a small heloc against one property as an emergency reserve.

Not trying to scare you but with experience (often bad) you will emerge strong and wise. 

Besides money for the downpayment, you will need money for initial repairs and maintenance, for an emergency fund for the property, and for the closing costs of the loan. 

With the dust settling from 2021 the composite data from the year is beginning to emerge.  

I'd say you want to be careful with tenant selection due to the current NYS State of Emergency and ban on evicitions.I recommend the following. 1.

With my mom, a type one diabetic, I have gone through so much with... from youth to now, from emergencies to doctor's visits, to help her cope with her own "personal life and relations."
